Hi,
We're using Jetspeed-current with Tomcat 5.0.30 for a CMS project.
Lately we have been letting in a couple of new test users and have
then received the stacktrace at the end of this message.
Settings:
JAVA_OPTS="-Xms64M -Xmx128M -Xloggc:/log/gb.log"
After responding to the stacktrace I upped the memory to Xms128M and
Xmx256M.
How many users are Jetspeed supposed to support with my memory VM
settings?
I also wonder how many mysql connections Jetspeed would need.
Sincerely
Eivinn Hustveit
